How do I Normalize mouse movement in Matlab from the browser (image processing)?

How do I Normalize mouse movement in Matlab from the browser (image processing)?

Would much appreciate help:

I am doing some image processing in Matlab, using information I pull from the matlab browser.

I am using this code to get the browser position

% top left corner
[top_left_brows] =...
    [browser_handle.getLocationOnScreen.getX,browser_handle.getLocationOnScreen.getY];
% width_height
[brows_width_height] =...
    [browser_handle.getWidth,browser_handle.getHeight];
brows_rectangle = [top_left_brows,brows_width_height];

Then I take a snapshot of what is in the browser with:

%# Set the capture area as the size for the screen
    rectangle = ...
        java.awt.Rectangle(brows_rectangle(1),brows_rectangle(2),brows_rectangle(3),brows_rectangle(4));
    %# Get the capture
    image = robo.createScreenCapture(rectangle);

Then I do some analysis on my image; the one I took the snapshot of.

I do some simple object recognition.

So far- so good

Now I want to interact with the browser using the mouse movement only.

That is easy enough using

robot.mouseMove

What I cannot do is normalise the mouse movement

I have three components; whole screen, browser & the figure that I am doing the image processing in:

The mouse is obviously set to work with the whole screen

I analyse my Figure and get a relative (to its own axis) position

I need to translate (normalise) that to the browser, but I dont even know if the browser has an ‘axes’ object.

I have tried moveptr, but there are too many gaps in my understanding. Will appreciate any help,
